The Non-Neustadtl Sonneborn-Berger score is a scoring system used in chess tournaments and is considered an improvement to the Neustadtl score proposed by William Sonneborn and Johann Berger. Sonneborn was a strong critic of the Neustadtl score, and suggested adding in the player's raw score. Berger supported this. However, adding in the raw score does no good when ranking tied players, and the suggestion died out and is seldom used today. However, the Neustadtl score is now commonly known as the Sonneborn-Berger score.
More common methods include the Neustadtl score, head to head, or favouring the player with the most wins. In Swiss system events, comparison of the Buchholz scores and the sum of progressive scores are common.
